    Abstract

    Despite some notable successes, only a fraction of the genetic variation
    available in wild relatives has been utilized to produce superior wheat
    varieties. This is as a direct result of the lack of availability of
    suitable high-throughput technologies to detect wheat/wild relative
    introgressions when they occur. Here, we report on the use of a new SNP
    array to detect wheat/wild relative introgressions in backcross
    progenies derived from interspecific hexaploid wheat/Ambylopyrum muticum F1 hybrids. The array enabled the detection and characterization of 218 genomewide wheat/Am. muticum
    introgressions, that is a significant step change in the generation and
    detection of introgressions compared to previous work in the field.
    Furthermore, the frequency of introgressions detected was sufficiently
    high to enable the construction of seven linkage groups of the Am. muticum
    genome, thus enabling the syntenic relationship between the wild
    relative and hexaploid wheat to be determined. The importance of the
    genetic variation from Am. muticum introduced into wheat for the development of superior varieties is discussed.
